Technical Field
[0001] This utility model relates to the field of hydraulic support push rod ear plate processing technology, and in particular to an auxiliary tooling for adjusting the angle of drilling oblique holes in hydraulic support push rod ear plates. Background Technology
[0002] Currently, in the field of hydraulic supports, the front end of the push rod is connected to the conveyor via a connector, and the rear end is connected to the hydraulic support base via a jack. The push rod moves and slides within a guide rail in the central space of the hydraulic support base, achieved by the extension and retraction of the jack. The push rod is a crucial connecting component of the hydraulic support. The push rod lug is an important part connected to the jack via a pin. Considering space constraints and the size of the jack cylinder, the holes on the push rod lug are designed as angled holes, such as... Figure 1 As shown, when this type of ear plate is placed in parallel, the drill bit is not perpendicular to the drilling surface. The push rod ear plate needs to be rotated to be perpendicular to the drill bit before drilling can be performed.
[0003] The existing simple device for drilling inclined holes in push rod lugs uses three steel plates welded together to form a U-shaped structure. Although this device can rotate the push rod lug angle to facilitate drilling on a vertical drilling machine, it has significant limitations because it does not consider the shape and size of the lugs and the angle of the drilling surface. It cannot adjust the drilling surface to a horizontal position, and the lugs are in line contact when placed. There are no protective devices on both sides of the lugs, making it easy for them to fall off and cause safety problems when drilling inclined holes.
[0004] The current problem to be solved is how to design an auxiliary tooling for adjusting the angle of the hydraulic support push rod ear plate for drilling inclined holes. This tooling should be ingeniously designed, simple in structure, and capable of adjusting different ear plate angles to reduce the difficulty of machining inclined holes, reduce the labor intensity of workers, improve production efficiency, and ensure operational safety. Utility Model Content
[0005] To address the technical problems existing in the machining of inclined holes in hydraulic support push rod lugs, such as the inability to adjust the required angle, lack of protective measures, high machining risks, and serious impact on production efficiency, this utility model provides an auxiliary tooling for adjusting the angle of inclined holes in hydraulic support push rod lugs. This tooling is ingeniously designed, simple in structure, and allows for adjustment of different lug angles, thereby reducing the difficulty of machining inclined holes, reducing the labor intensity of workers, improving production efficiency, and ensuring operational safety.

The slider, connecting rod, lug A, V-shaped seat and lug B constitute a crank slider mechanism. The opening direction of the V-shaped seat is changed by the back and forth movement of the slider in the long slot of the slide plate.
[0007] As a further optimization of the auxiliary tooling for adjusting the angle of the inclined hole drilled in the aforementioned hydraulic support push rod ear plate, a T-shaped locking bolt is provided at the front and rear of the slider, and a matching locking nut is provided at the lower end of the T-shaped locking bolt.

[0009] As a further optimization of the auxiliary tooling for adjusting the angle of the inclined hole drilled in the aforementioned hydraulic support push rod ear plate, one end of the V-shaped seat opening extends outward to form a support rod, and the support rod is provided with a clearance hole for drilling the inclined hole in the push rod ear plate.
[0010] As a further optimization of the auxiliary tooling for adjusting the angle of the inclined hole drilled in the aforementioned hydraulic support push rod ear plate, the lower part of the V-shaped seat is provided with a through hole, and a protective plate is provided on the left and right sides of the V-shaped seat respectively. The protective plates are fixed to the two sides of the V-shaped seat by connecting bolts and connecting nuts.
[0011] As a further optimization of the auxiliary tooling for adjusting the angle of the inclined hole drilled in the aforementioned hydraulic support push rod ear plate, the slide plate is fixed to the support platform around its perimeter by fastening screws.
[0012] Compared with the prior art, the beneficial effects of this utility model are:
[0013] I. This utility model includes a support platform, a slide plate, a slider, multiple connecting pins, a connecting rod, an ear plate A, a V-shaped seat, connecting bolts, connecting nuts, a support base, and an ear plate B.

[0024] The specific embodiments of this utility model will be further described in detail below with reference to the accompanying drawings.
[0025] like Figure 1 and 2 As shown, Figure 1 This is a schematic diagram of the three-dimensional structure of the push rod lug; Figure 2 This is a schematic diagram of a simple fixture for drilling inclined holes in existing push rod lugs. The surface of the inclined hole 18 on the push rod lug is not perpendicular to the drill bit of the vertical drilling machine. When machining with the vertical drilling machine, the drill bit experiences uneven force and is prone to slippage, requiring angle adjustment to make the inclined hole surface perpendicular to the vertical drill bit. While the simple fixture allows for rotating the push rod lug to make the drill bit perpendicular to the inclined hole 18 surface, it still has significant limitations due to the variety of lug shapes, sizes, and drilling angles. There are instances where the drilling surface cannot be adjusted to a horizontal position. Furthermore, when the push rod lug is placed in this simple fixture, the push rod lug 17 is in line contact with the bottom edge of the device, and there are no protective plates on either side of the lug, making it easy for the push rod's center of gravity to shift and tilt, resulting in poor safety.
[0026] like Figure 3 , 4 As shown, Figure 3 This is a three-dimensional structural diagram of the present invention; Figure 4 This is a schematic diagram of the three-dimensional structure of the slider; the auxiliary tooling for adjusting the angle of the inclined hole drilled in the lug plate of the hydraulic support push rod includes a support platform 1, a slide plate 2, a slider 6, multiple connecting pins 7, a connecting rod 9, a lug plate A10, a V-shaped seat 11, connecting bolts 13, connecting nuts 14, a support base 15, and a lug plate B16. The slide plate 2 is fixed to the support platform 1 around its perimeter by fastening screws 3. The slide plate 2 has an elongated hole. The lower end of the slider 6 has an outwardly protruding part that matches the elongated hole. The upper end of the slider 6 has a shallow groove for installing the lug hole of the connecting rod 9. Through holes are opened on both sides of the shallow groove. The connecting pins 7 pass through the through holes and the lug hole of the connecting rod 9 in sequence to fix the lower end of the connecting rod 9 in the shallow groove of the slider 6. A support base 15 is provided on one side of the elongated hole of the slide plate 2. A through groove is opened on the upper end of the support base 15. The lower end of the V-shaped seat 11 has downwardly protruding parts on the front and rear sides respectively. Ear plates B16 and A10 are movably connected to the support base 15 and the upper end of the connecting rod 9 respectively via connecting pins 7. The connecting pins 7 are equipped with cotter pins 8 for locking. The slider 6, connecting rod 9, ear plate A10, V-shaped seat 11, and ear plate B16 constitute a crank-slider mechanism. The slider 6 moves back and forth within the elongated hole of the slide plate 2, thereby rotating ear plates A10, V-shaped seat 11, and ear plate B16, and thus adjusting the angle of the push rod ear plate. After sliding the slider 6 left and right to adjust the angle of the push rod ear plate's oblique hole to a suitable position, the T-shaped locking bolt 4 and locking nut 5 are tightened to fix the position of the slider 6. Oblique hole machining can be achieved simply by clamping and fixing the push rod ear plate while keeping the position of the slider 6 unchanged.
[0027] like Figure 4 As shown, a T-shaped locking bolt 4 is provided at the front and rear of the slider 6, and a matching locking nut 5 is provided at the lower end of the T-shaped locking bolt 4. The slider 6 is fixed at the set position by the cooperation of the T-shaped locking bolt 4 and the locking nut 5.
[0028] like Figure 5 As shown, Figure 5 This is a schematic diagram of the three-dimensional structure of the V-shaped seat. One open end of the V-shaped seat 11 extends outward to form a support rod, which has a clearance hole 19 for drilling inclined holes in the push rod lug plate. The plane containing the inclined hole 18 on the push rod lug plate 17 is not perpendicular to the drill bit of the vertical drilling machine. When machining with a vertical drilling machine, the drill bit experiences uneven force and is prone to slippage. The angle needs to be adjusted to make the plane containing the inclined hole perpendicular to the vertical drill bit. The push rod lug plate 17 is placed on the V-shaped surface of the V-shaped seat, resulting in surface contact, a large contact area, and uniform force distribution, facilitating drilling.
[0029] The V-shaped seat 11 has a through hole at its lower part, and a protective plate 12 is provided on each of the left and right sides of the V-shaped seat 11. The protective plates 12 are fixed to the sides of the V-shaped seat 11 by connecting bolts 13 and connecting nuts 14. The push rod ear plate 17 is placed on the V-shaped seat 11 and fastened to the protective plate 12 with connecting bolts 13 and connecting nuts 14 to prevent the push rod ear plate from tilting or tipping over during drilling.
[0030] like Figure 6 , 7 As shown, Figure 6 This is a schematic diagram showing the position of the push rod lug when the slider is at the right end; Figure 7 This is a schematic diagram of the position of the push rod ear plate when the slider is at the left end; the slider 6 can be moved to the left and right to adjust the angle of the push rod ear plate from the initial position to the final position. Then, the slider 6 can be fixed by locking it with T-type locking bolt 4 and locking nut 5, and the drilling of the angled hole can be carried out.
[0031] The usage process of this utility model is as follows: Place the push rod ear plate 17 on the V-shaped seat 11, and fasten it together with the protective plate 12 using the connecting bolts 13 and connecting nuts 14 to prevent the push rod ear plate 17 from tilting or tipping over during drilling; move the slider 6, and after adjusting the angle of the push rod ear plate to a suitable position, tighten the T-type locking bolts 4 and locking nuts 5 to fix the position of the slider 6. By simply clamping and fixing the push rod ear plate while keeping the position of the slider 6 unchanged, the angled hole machining can be achieved.
[0032] In practical applications, this tooling uses common sheet metal, pins, and fixing bolts, making it easy to process. The pins and bolts used for rotation are all standard parts, resulting in low manufacturing and processing costs and low operation difficulty. It can adjust the angle of the push rod ear plate to drill oblique holes, which can greatly reduce the difficulty of oblique hole processing, reduce the labor intensity of workers, improve production efficiency, and ensure operational safety.
[0033] This utility model has an ingenious design and simple structure. It can adjust different ear plate angles, reduce the difficulty of machining oblique holes, reduce the labor intensity of workers, improve production efficiency, and ensure operational safety. It solves the technical problems existing in the machining of oblique holes in the ear plates of hydraulic support push rods, such as the inability to adjust the required angle, lack of protective measures, high processing risks, and serious impact on production efficiency. Compared with existing technologies, it has a good market prospect and development space.

However, the present invention is not limited to the above embodiments and examples. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the concept of the present invention.
